Check Digit Verification of cas no

The CAS Registry Mumber 111-33-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111-33:
(5*1)+(4*1)+(3*1)+(2*3)+(1*3)=21
21 % 10 = 1
So 111-33-1 is a valid CAS Registry Number.

New method for preparing N,N'-dimethylethylenediamine and N,N'-dimethyl-1,3-propanediamine

-

Paragraph 0015-0020, (2019/10/01)

The present invention relates to a new method for preparing N,N'-dimethylethylenediamine and N,N'-dimethyl-1,3-propanediamine, wherein 1,3-dimethyl-2-imidazolidinone or 1,3-dimethyl-tetrahydro-2-pyrimidone is used as a raw material, a suitable alkali is added, and a heating ring-opening reaction is perform to prepare N,N'-dimethylethylenediamine and N,N'-dimethyl-1,3-propanediamine. In the prior art, the conventional method performs alkylation by using the amine as the raw material to generate more by-products. According to the present invention, the method completely avoids the problem in theprior art, has characteristics of simple operation, high yield, less three-waste and high product purity, and is suitable for industrial production.

SATURATED N-HETEROCYCLIC CARBENE-LIGAND METAL COMPLEX DERIVATIVES, PREPARING METHOD THEREOF, AND PREPARING METHOD OF SILANE COMPOUND BY HYDROSILYLATION REACTION USING THE SAME AS CATALYST

-

Page/Page column 13, (2011/07/30)

Provided are a saturated N-heterocyclic carbene-ligand metal complex derivative, a method for preparing the same, and a method for preparing a silane compound by hydrosilylation using the same as a catalyst. To describe in more detail, the metal complex derivative has a saturated N-heterocyclic carbene derivative and an olefin ligand at the same time. A silane compound is prepared by hydrosilylation in the presence of the metal complex derivative as a catalyst. The provided metal complex derivative of the present invention has superior stability during hydrosilylation reaction and is capable of effectively performing the hydrosilylation reaction at low temperature even with small quantity. Further, a product with superior regioselectivity may be obtained. In addition, after the hydrosilylation reaction is completed, the metal complex derivative may be recovered and recycled.

Episulfide compound, method for producing the same and optical product comprising the same

-

, (2008/06/13)

The invention relates to a novel episulfide compound useful as a starting material for optical materials that have a high refractive index and a high Abbe's number and to provide a method for efficiently producing the same and an optical product comprising the same. The episulfide compound represented by the general formula (1) : wherein EP represents and n is an integer of from 0 to 2, and the method for producing the episulfide compound represented by the general formula (1) comprises reacting a mercapto group-having episulfide compound with 2,4,6-trimethylene-1,3,5-trithiane.
